Substantiation of Improvements for the Bearing Structure of an Open Car to Provide a Higher Security during Rail/Sea Transportation

This article presents the most frequent damage in bearing structure of a rail car during rail/sea transportation. The study includes load modes for an open such as unloading with grab and transportation by train ferry. It was found that vulnerable element is top cord. authors suggest applying viscous material (an elastomer) to reinforce solution confirmed means strength calculation, whose results showed efficiency solution. ferry can be protected mounting special fixation units on bolster beams. geometry chosen according chain binder. calculation demonstrated provided application suggested. also experimental determination improved based finite method full-scale bench testing. research conducted might used those who are interested higher operational cars
